I used this set of slides for a presentation at MooseDay 2013 (April)

1. humane assessment humane-assessment.com by example the missing method for making software engineering decisions
2. assessment development
3. craft analysis processes daily spike strategic facilitator stakeholder organization tooling buildup throwaway assessment
4. daily architecture violations
5. daily architecture violations naming conventions
6. com.company common module core whatever name srv ui inter whatever
7. com.company common module core whatever name srv ui inter whatever model allModelNamespaces select: [:each | (NamingConventionGrammar new matches: each mooseName) not]
8. spike improving a cache
